Williams spent the past year as a Tennessee Titans’ defensive assistant. He replaces Tim Walton, who was let go after just one season on Wednesday.

This is a move that was first set in motion in 2012, but was quickly derailed in the wake of Bountygate. Williams and head coach Sean Payton were both suspended by the NFL for their roles in the activity.

Williams was hired then by the Rams, but was let go once his suspension was made official.

Williams will get to work with one of the most talented young defensive groups in the NFL, and one of its best players overall in end Robert Quinn. He is an aggressive coach who’ll bring a clear edge to the Rams.
